To all whom it. may concern.- 7 Be it known thatl, OLE HANSEN, acitizenof the United States, residing at Walnut Grove,-in the county ofSacramento and State of California, have invented 'a new and usefulF1re-Escape,of which the following is aspeci- .fication.

' My invention relates to"improven1ents in {fire-escapes in whichfolding ladders are emplayed and so constructed as to conform to thearchitecture of the building to which they are attached when .the sameof use."

are folded up and'out reference to the accompanying drawings, in whichpI Figure 1 is a perspective elevation of a 'My invention will 'bereadiiy understood by i building with my improvement attached. Fig. 2 is aside elevation of a portion of the ladder to show the side view of thebrace which serves to keep the ladder from swinging or swaying sidewise,and is employed near'the top or bottom of the ladder. Fig. 3

is a plan view of the same as that shown in Fig. 2. Fig. 4 is a sideelevation showing 'a portion of the ladder and partially raised as "in.the aetof folding. Fig. 5 is a portion'of the outer rail of the ladderto show theatta-chment of a projection'conforming to a pro Fig. 6 is aside ele -vation of a portion of the ladder, showing a- H raising thesame.

pinion and segment attached as one mode of Fig. 7 is a side elevatinn ofportion of the ladder with a broken part of the folding platform orwindow-step. Fig. 8 is a detail View Ora window; showing the foldingplatformor window-step as it appears when the ladder is opened out,ready for use. Fig. 9 is, aportion of the ladder-strip employed .toattach thefolding ladder to ahouse I already constructed. Flg.j1() is avertical 3 plan jview;s howing a section of the same as that showhinFig.9.

Ihe following is the construction-of the same: I'form' the ladder -'of-metal,-the outer of the "ladder when folded up' in the front wall ofthebuildinglyattach any suitable employ 'several difierent modes of'operating "the ladder, according to the construction and arrangement ofthe house. I raise and lower .or open the same by the segment and pinion5 1 at D in the inner strip or ladder-rail, E. I

F and G. (Shown in Figs. 4 and 6.) I balance the weight of the outerrail, A, by-the weight H. (Shown in Figs. 1 and 4.) I attach the bell Iand arrange the arm or lever J' to strike the same as the pulley K isrevolved by the ladder-cord L, passing over it as the ladder opens out.I-attach the platform L" under the windows and pivot it to work upon thesame line or axis as the rounds of the ladder, so that when the lad- '70der is opened out a platform widee'nough to step out upon is just alittle below the window-sill, connected with the ladder by the trails Mand.N,. leaving a space at the end between the platform and the ladderto pass down through. I employthe portable ladder-strip R with flangesES to receive the rounds Z. I attaeh'the strip R by means of the bolts Vor similar attachment. I

sometimes employ thelever orarm J to .strike or setofl any. well-knowncoil-spring or other alarm,,so as to makesufiicient noise to alarm thewhole house instantly, instead of employing the common bell, I.

The following-is the -.operation' of my fireescape: When a fire isdiscovered; the segmeut F is operated by means of the pinion G, or anywell-known device for throwing the ladder out andvdown until the outerrail, A,

rests upon the ground andthe rouhdsof the ladder lie in a horizontalposition. The plat-form L is in position to allow a person to step outupon the platform and descend the ladder between the arms M and N. Theplatform. L serves as a firm brace to theladderto, 5
